D. MAN
Explanation:
A local area network (LAN) refers to a group of personal computers (PCs) or terminals that are located within the same general area and connected by a common network cable (communication circuit), so that they can exchange information from one node of the network to another. A local area network (LAN) is typically used in small or limited areas such as a set of rooms, a single building, school, hospital, or a set of well-connected buildings. Some of the network devices or equipments used in a local area network (LAN) includes an access point, personal computers, a switch, a router, printer, etc.
On the other hand, a metropolitan area network (MAN) is formed by an aggregation of multiple local area network (LAN) that are interconnected using backbone provided by an internet service provider (ISP). A metropolitan area network (MAN) spans for about 5 kilometers to 50 kilometers in size.
Basically, a metropolitan area network (MAN) spans across a geographic area such as a city and it's larger than a local area network (LAN) but significantly smaller than a wide area network (WAN).
In conclusion, the network type that the patrol services of a city's police department would most likely use is a metropolitan area network (MAN).
<u>Answer:</u>
<em> </em><em>Modem is an hybrid device,</em><em> which is responsible for modulating and demodulating information. </em><em>It is a transmission medium and also it is a hardware tool used for connecting to internet.</em>
<u>Explanation:</u>
What is modulation?, let us understand. The <em>process of converting analog to digital signal is called modulation and demodulation is vice-versa.</em> The computer connects internet classically using telephone wire.
The <em>telephone wire understands only analog signal and a computer understands only digital signal.</em> So Modem’s role is to take care of this aspect while <em>connecting to the internet.</em>
